单项选择题
A two-node cluster is configured for mutual takeover with two service IP labels. The cluster is Being tested for fallover behavior. Both nodes in the cluster have two network interfaces （ent0’ and ’ent1’） configured with IPAT via IP Replacement. When the network cable is removed from the interface card with the service address （’ent0’）， the service address is moved to ’ent1’， and ’ent0’ is reconfigured on its boot address. When the network cable is replaced on ’ent0，the service address does not switch back to ’ent0’. What statement most accurately describes this situation？（）
A. EtherChannel is needed to automatically switch the service IP address back to ’ent0’.
B. This is the default behavior for a network interface failure with this configuration.
C. Gratuitous ARP support needs to be enabled for the IP Network Interface Module in SMIT.
D. The Inactive Network Takeover option should be set to "true" to forece the service address back to ’ent0’.

Company.com has a non-IBM disk storage unit connected by two Fibre channel connections. The Nodes have multiple connections to the storage device that allow load balancing. A failure with one Fibre adapter or connection will not be noticed by the application， but it needs to be addressed. How can HACMP help make this environment more robust？（）
A. Customize disk heartbeat methods to detect disk adapter failures.
B. Customize an error notification method that monitors for volume group quorum loss.
C. Customize an error notification facility to act on the event when reported to the error log.
D. Customize a HACMP event script to monitor the disk connections and cause a fallover if there is a failure.

Company.com wishes to use IPAT via IP replacement in a two-node mutual cluster. Each node has two Ethernet 10/100/1000 adapters. Throughout the planning session，the customer has asked questions about subnet and VLAN requirements for the intended network topology. Which of the following best describes the network requirements？（）
A. The service IP addresses must be on a separate subnet and VLAN.
B. The non-service and service IP addresses must be on the same subnet and on the same VLAN.
C. All interfaces on a node must be in different subnets. All subnets must be on the same VLAN.
D. One non-service and one service IP address must be on the same logical subnet. All interfaces must be on the same VLAN.
单项选择题
Using the C-SPOC utilities， an administrator has created a new volume group and filesytems. Theadministrator performs an Isvg -I command on the volume group and notices that the log logical volume created in C-SPOC is closed/syncd and loglv01 has been created and is in use. What step was required in order for the logfile created by C-SPOC to be used.（）
A. Perform the C-SPOC logform utility option prior to creating any filesystems.
B. Manually perform a logform outside of C-SPOC prior to creating any filesystems.
C. Run a logredo command and select log logical volume created in C-SPOC as the preferred jfslog.
D. Use C-SPOC to delete and recreate the log logical volume，set the perform logform option to true.

The first step documented in Company.com’s HACMP test plan is to start the cluster manager on the normal service node and verify that HACMP daemons have started with the ’lssrc -g cluster" command. What daemons MUST show as active in the ’lssrc -g cluster" command to have an operational cluster？（）
A. clstrmgrES，clsmuxpdES
B. topsvcsd，grpsvcsd，exaixos
C. topsvcsd，grpsvcsd，clinfoES，grglsmd
D. clstrmgrES，clsmuxpdES，topsvcsd，grpsvcsd
